REED non Looms.

Specification of Letters Patent.

Patentedfict. 26, 1915.

Application filed July 21 1915. 1 Serial No. 41,086.

To all whom it may concern Be it known that I, EMIL WnrnRsnAus, manufacturer, residing at Heckinghausenstrasse, Barmen-Rittershausen, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Reeds for Looms, of which the following is a specification.

My invention relates to that kind of reeds for looms, whose single reed dents are inserted between the windings of coils and are held by lateral guide-rods which up. to a certain depth engage into side grooves of the reed dents and are partially maintained in place by the windings of said coils. Owing to this arrangement said lateral guide-rods rest in a channelwhich is formed on the one hand by the windings of the coils and on the other hand by the edges of the grooves of the single reed dents.

Now, the present invention intends to avoid the drawbacks connected with the above-mentioned reeds, which principally work necessary for replacing the reed dents which have become damaged is rendered much easier and the other reed dents at their ends remain in connection with the coils.

According to my invention thesaid'advantages are obtained in such a way that at the upper and lower part of the reed dents two guide-rods are arranged, the one of said guide-rods engaging into a groove formed in the front face of the reed dents, while the other guide-rod engages into a groove situated in another plane and formed in the posterior face of said reed dents. In this way each reed dent is held at its upper and lower part by two guide-rods laying in different planes, and the guide-rods and the grooves may be given a pretty great diam eter without the resistance ofv the reed dents being too much decreased. Owing to the duplicate arrangement of the guide-rods at both ends of the reed dents a slackening of reed dents during the working is prevented. Nevertheless it is possible to easily and readily replace some or other reed dents without disturbing the position of the other reed dents.

Another feature of my invention consists in surrounding the guide-rods and the coils on both sides by metallic strips or hands of a form corresponding to said guide-rods and coils, saidmetallic parts being composed of two pieces, the one piece being provided with bent flaps connected at their ends with front-plates so as to form a casing, said casing being loosely connected with the other piece owing to the fact that the guide-rod engages in bent flaps arranged at both ends of said second piece. After removal of the second piece the reed dents can easily be taken off without an undesired alteration of their position being possible.

In the accompanying drawing forming a part of this specification and in which similar letters of reference relate to corresponding parts throughout the several views, Figure 1 is an elevation, Fig. 2 a side view of a form of execution of my improved arrangeinent.

In Fig.2 the upper portions of the metallic strips or hands inclosing said guiderods and 'coils are represented as being broken 0a.

As already mentioned, the single reed dentsjc'i'of. the reed are inserted above and below between the single windings of the coils b which in a known manner are provided in duplicate arrangement and have opposite windings; Further, also in a known .manner, the reed dents are prevented against lateral displacement by rods or bars 0, 0

being passed through the windings of the coils. The rods or bars 0 which may be of circular or quadrangular cross section are arranged in different horizontal planes than the rods or bars 0 and engage in corresponding grooves formed in the reed dents. As a consequence of this arrangement the reed dents are secured against vertical displacement in the reed and obtain a quite reliable mutual connection. Owing to the arrangement of the grooves a, in different horizontal planes a too great diminishing of the cross-section of the reed dents is prevented.

The longitudinal faces of the reed are in a known manner provided at their upper and lower parts with metallic strips or bands, whose configuration exactly corresponds to the form of the coils, so that said metallic strips or hands rest against the reed. According to my invention said metallic strips or bands are divided longitudinally in two halves. The one part (Z is provided with flaps 03 forming a casing with vertical bars 6, around which said flaps d are bent. Opposite to the part d on the other side of the reed, the other parts or halves of the metallic strips or bands of corresponding shape and forming a cover f are arranged, said parts 7 being also provided with vertically bent flaps f", Said flaps f are provided with apertures through which are inserted the ends of the rods or bars 0, so as to firmly connect said flaps f with the casing or frame. In this way, a very easy connection and disconnection of the cover parts 7 is afforded. Said cover parts f are also provided at their outer ends with a vertically bent flange f covering the extremity of the reed dents.

For replacing a damaged reed dent by another it is only necessary to remove the cover part 7 after having drawn out a small portion of the rod 0, and, on the rod 0 having been further laterally drawn out until the reed dent which is to be removed being reached, the reed dent can be readily taken off from above or below and the new reed dent can be set in place without difficulty. Owing to the fact that the windings of the coils are opposite and that the other lateral guide-rods remain in place the diflerent parts of the reed are held together in a very efficient manner.

What I claim and desire to secure by Letters Patent of the United States 1. In a reed for looms, a pair of spaced bars, said bars having a pair of oppositely disposed recesses at each end and in the edge portions thereof, coils between the ends of said bars, reed dents positioned between the bars with the extremities thereof fastened between the convolutions of the coils, said reed dents having oppositely disposed recesses in their edges corresponding to the recesses of the bars, and connecting members for the bars and reed dents and passing through the coils, said connecting members engaging the recesses.

2. In a reed for looms, a pair of spaced Copies of this patent inay be obtained for 'five cents each, by addressing the bars, said bars having a pair of oppositely disposed recesses at each end and in the edge portions thereof, coils between the ends of said bars, said coils having opposite windings, reed dents positioned between the bars with the extremities thereof fastened between the convolutions of the coils, said reed dents having oppositely disposed recesses in their edges corresponding to the recesses of the bars, connecting members for the bars and reed dents and passing through the coils, said connecting members engaging the recesses, and removable casing parts inclosing the coils and connecting members at the ends of the bars and reed dents, and adapted upon limited displacement of the connecting members to be removed and also to permit removal of any one or ones of said reed dents.

3. In a reed for looms, a plurality of vertical front bars having recesses in opposite edges thereof located on dilferent horizontal planes, there being two of said recesses near each end of each bar, a pair of oppositely wound coils between the corresponding ends of the bars, reed dents having their ends provided with corresponding pairs of recesses and engaged through alined convolutions of the coils, and guard strips at opposite edges of the reed surrounding the coils and each having flaps at the end thereof provided with apertures, and rods extending through the coils engaging the respective recesses of the bars and reed dents, said rods being adapted to be displaced longitudinally with respect thereto so as to disengage the end portions of the guard members to permit removal of the latter, further displacement of the rods past any of the respective reed dents, permitting removal of the latter from the top or bottom of the reed by disengagement from the respective coils.

In testimony whereof I aflix my signature in presence of two witnesses.
